Mounted onthe truck platform is a usual derrick mast 9 comprising upright sidemembers Ill, transverse frame members l I, and cross brace members l2,and the mast is pivoted at IS on a base structure |4 carried by thetruck platform to swing downwardly into a lowered transport position onthe truck in a manner well known to those skilled in the art. The rodline '8 passes through and is adapted to be rotated during drilling bythe rotary table vI, also in a well known manner, and comprises a plu-'rality of rods l5 coupled together at l6 by a conis one-end of a spinninline or cable 48.

4 may be modified to provide different speed ratios to suit differentoperating conditions. The block frames have guide openings 42 throughwhich the guide rods pass so that the pulley frame 4| of the lower block2| serves in effect as a sliding cross head. Carried by a cross member44 of the mast base structure I4 is abracket 4.5;, on which a guidepulley 4'6 is journaled,-and this pulley is arranged in angular relationwith respect to the puneys of the pulley block. Attached to the bottomof the frame 36 of the upper pulley block 30 is an eyebolt 41, andconnected to this eyebolt This cable extends downwardly from its pointof atventional coupling usually embodying coacting.

threaded parts on the adjacent rod-ends. The

so that considerable effort is necessary to effect loosening thereof.The rotary table is driven through suitable transmission connectionsfrom conventional engines l1, l1 carried by the truck. In rotary drillsof the character disclosed, a fluted or grooved grief stem or kelly isusually attached to the upper endof the rod line, and the rotary table Icarries a usual driving bushing which engages the flutes orgrooves ofthe grief stem so that the latter may be rotated as it slides throughthe table. When it is desired to "add an additional rod to the rod lineor to withdraw the rod line from the drill hole, the grief stem isdetached from the rod line, and slips l8 are fitted in the table forsupporting the rod line while it is being withdrawn from the hole. Asthe rod line is withdrawn, the joints l6 between the rods must bequickly disconnected, and after the joints are broken or loosened by theusual make and break tongs, it is desirable to spin rapidly the rod tobe uncoupled in order to save time. Also during coupling of the rods, asthe rod line is lowered into the hole, spinning in of the rods issimilarly desirable.

Now referring to the improved spinning apparatus l for quicklycompletely uncoupling or for coupling the rod joints, it will be notedthat extending vertically lengthwise of the derrick mast 9, when thelatter is in its erect operative position shown, at one side thereof isa guideway for a reciprocable pulley block 2 l of a multiple reeve,speed multiplying, cable andpulley mechanism 22. This guideway, in thisinstance, comtaohment with'the upper pulley block around the pulley 31of thel ower pulley block, then extends upwardly .and passes around thepulley 32 of the upper pulley block, and then extends downwardly aboutthe pulley 38 of the lower block. The cable then extends upwardly aroundthe pulley 33 of the upper block, then-downwardly around the pulley 39of the lo'werbloc'k, and then upwardly-around the'pulley-3'4'of theupper block prises parallel guide rods 23, 23 rigidly attached at 24 attheir u per ends to an up er frame mermber 25 preferably secured to atransverse frame member of the derrick'mast and at their lower ends at25 to lugs 21 secured to a cross frame member 28 located at the mastpivot. Loosely surrounding the lower portions of these guides are stopsleeves 29 which provide bottom stops for the guide pulley block 2| inan obvious manner. The cable and pulley mechanism 22 further includes arelatively stationary top pulley block 30 attached by a bolt 3| t0 theupper frame member 25, and carrying a plurality of, herein, preferablythree, rotatable pulleys 32, 33 and 34 suitably journaled in'coaxialrelation on a cross shaft 35 carried by the upper block frame 36. Thelower guided pulley block is reciprocable longitu dinally along thegiude rods 23, 23 and carries'a. plurality of, herein preferablythree,'pulleys13'|, 3B and 39 suitably journalled in coaxial relation ona cross shaft 40 carried bya lower block frame 4|. It will be evidentthat the number of the" pulleys and the arrangement of the pulley blocksand has its drop lin'e extending downwardly from the rear side'of the"top pulley 3 to the'guidepulley on the mast base structure H4. The"cable extends substantially horizontally from the guide pulley 46 to therod line' 8 wherein its intermediate portion is tightly wrapped aroundor coiled about,at 49, the rod to be rotated, and the free end of thecable extends outwardly at 50 in such manner as to be grasped and heldtaut by" the operator during the rod spinning operation.-

The improved spinning apparatus is fluid pres sure operated, and thereis a vertical fluid cylinder 5| secured at 52 at its lower end to'thetop of the'table bed frame 6 and held at its upper end by 'a U-bolt 53attached to the cro'ss'frame 44 of the mast base structure I4. Containedin this cylinder is a reciprocable piston 54having its piston rod 55extending upwardly and outwardly through the top cylinder head'andcoupled at 56 to the lower end of a'cable 'connection'5l, the latter inturncoupled at 58 toan eyebolt 59 attached to the bottom of the pulleyframe 4| of the lower pulley block 2|; The fluid syste nwith which thecylinder is associated is shown somewhat diagrammatically in Fig. 7, andcomprlsesa conventional valve block 60 secured to the top'ofthe tablebedframe at the s'id'e'op posite'from thespinning apparatus, and havingits supply chamber connected by a conduit 6| to the discharge side of aconventionalpump 52,

herein a liquid pump, carriedby the-truck and having its intakeconnected to'a suitable liquid tank 63.- A discharge conduit 54 leadsfromfthe valve box back to the tank, This valve block con tains aconventional control valve -having a suitable operating handle '65 (Fig;1). Leading from the valve block areconduits 61 and 88 con nected to theopposite endsof the cylinder 5|, as clearly shown, .so that when' thevalve is'properly positioned, the piston 54 may be moved under theinfluence of liquid under pressure in the cylinder either upwardly ordownwardly as desired. The fluid system embodies conventional reliefvalves which may be adjusted in a known mannerso that apredeterminedpressuremay be applied=to the piston 54, which pressure ismain- 7, horizontally fromsaid'guid'e' pulley and adapted to 'becoiledabout a drill rod to be spun with its free endheld taut by the operator,and means for efiecting fluid supply to said cylinder to effect downwardmovement of said piston and said lower-pulley block thereby to draw inthe end of the cable coiled about the drill rod to spin the latter. l
